<p>The invention relates to a method for coding digital data, using an algorithm for coding according to blocks having a predefined fixed length (d). The invention more specifically relates to the coding of a residual block stemming from the decomposition of a packet of data blocks having a predefined fixed length (d). The inventive method comprises the following steps: forming a combined block (BC) having a predefined fixed length (d), said combined block having a known predefined value which is independent from the data to be coded; coding the combined block (BC) in order to form a coded combined block (BC'); removing a useful part (PU) of the coded combined block (BC'), said useful part having a length (e) which is equal to the length of the original residual block (BR); combining said useful part (PU) of the coded combined block (BC') with the residual block (BR) in order to obtain a coded residual block (BR') having the same length (e) as the original residual block (BR).</p> |
